Yeah... this is just asking for a flame war. And do you know how much of these threads have had been made? Go look at previous threads. And, I'll tell you this, the PS3 wins, and then the 360 fans get upset.
I think the best bang for your buck right now would be the PS3. Only because of the free online play, included wireless capabilities and the blue-ray player. I am not sure which one is better overall though. Each has its pros and cons.
